Title: Administering a gravity segregation dispersion by continuous infusion
IPC: A61K49/06
Filed: 2000-08-25
Abstract: Method and apparatus for continuous infusion to a subject of dispersions in which the dispersed phase is susceptible to flotation or sedimentation. The dispersion is controllably delivered from an upper or lower extremity of an essentially vertically positioned delivery vessel, e.g. syringe 2, and is then admixed with flushing medium, e.g. from infusion minibag 8, prior to administration to the subject. Vertical positioning of the delivery device maximises the distance through which flotation or sedimentation may occur, thereby substantially reducing the effects of separation over a given period of time compared to use of a corresponding horizontal delivery vessel such as a syringe placed in a conventional syringe driver.
